WAGON- BRAKE.

SPECIFICATION forming part of Iletters Patent No. 691,547, dated January21, 1902.

Application filed July 22.11901.l Serial No. 69,239. (No model.)

To all whom it may concern.:

Be it known that l, JOHN HENRY JENNER, a citizen of theUnitedStates,residing at Leavenworth, in the county of vCrawford and State ofIndiana, have invented certain new and useful Improvements inWagon-Brakes and I do declare the following to be a full, clear, and eX-act description of the invention, such as will enable others skilled inthe art to which it appertains to make anduse the same.

The object of my invention is to provide a Wagon-brake which is simpleof construction, easily and conveniently operated, and adapted to bequickly applied and removed.

To this end the invention consists of certain novel features ofconstruction, combination, and arrangement of parts, as will behereinafter more fully described,and particular view on line 4 4 of Fig.2.

Referring now more particularly to the drawings, the numeral 1designates the rear axle, the numeral 2 the rear wheel, and the numeral3 the rear hounds of a wagon or vehicle of ordinary or any preferredconstruction.

Pivotally mounted upon the forward portion of the handle 3 is atransverse bar 4, which is provided with loops or bearings 5, in whichis mounted a swinging yoke or hanger 6. This hanger is of U form and hasits arms projecting downwardly, and to'said arms is connected by upperand lower sets of nuts 7 and 8 the brake-beam 9, carrying the brakeshoes10, which are adapted to bear against the wheels 2. By this constructionthe brakebeam is mounted to swing upon the bar 4 toward and from thewheels 2 and may be applied to and released` from the hanger 6 byapplying or releasing the nuts 7 and 8 in a manner readilyunderstood.Thebrake mechanism, with the exception of a single brakerod, is mountedupon said beam, so that it can be applied to and removed from the framewith the beam.

Journaled in bearings 1l upon the rear portion of the beam 9 is a shaft12, provided with cranks13 and 14. The crank 13 is joined tolthe forwardend of a brake-rod 15, which is connected at its rear end to the rearaxle 4. The crank 14 carries loops or sockets for the reception of .ahand-lever 10, which is suitably secured thereto, so that by operatingthe lever back and forth the brake-shoes will be operated and releasedin the manner hereinafter described.

Pivoted to the crank-arm 14 is a ratchettoothed L-shaped bar 16, theteeth of which are adapted to engage or slide upon a fixed pawl orprojection 17 on the front edge ofthe beam 9. This ratchet-toothed barhas connected thereto a rod 18, which is operated by a pivotedhand-lever 19 to engage andrelease the bar whenever desired.

In operation, when the lever 10 isthrown forwardly the crank-shaft 12 isturned to bring the crank 13 to an upright position, whereupon thebrake-beam 9 is drawn rearwardly and the brake-shoes 10 brought intocontact with the wheels 2. When, on the other hand, the lever is thrownrearwardly,

the crank 13 is moved toa horizontal position,

lengthening, instead of decreasing, the distance between the brake-beam9 and the rear axle 4, thus causingthe brake-beam to swing forwardly onthe movable hanger 6 and to thereby withdraw the brake-shoes fromengagement with the wheel. When the crankshaftris adjusted to thedesired position to hold the brake in and cnt of action, theratchet-toothed baris engaged with the fixed pawl to hold said shaftagainst movement, and when this is done the brake-beam is prevented fromswinging and the brake-shoes are held in engagement with the wheels.When the lever is thrown in the opposite direction to release thebrake-shoes fromengagement with the wheel and the ratchet-toothed bar isengaged with the fixed pawl,the shaft is also held against movement andthe brake-beam thereby held retracted and prevented from swinging on thetransverse bar 5. Any other suitable form of latch mechanism may beemployed in place of the fixed pawl and ratchettoothed bar to performthis function.

When the brake mechanism is used upon IOO box vehicles, the operatinghandle or lever herein shown may be dispensed with, and suitableconnections provided by which the crank-shaft may be operated from thefront of the vehicle.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of the invention will be readily understood, and it will beseen that the invention provides bra-ke mechanism of which the operatingparts are carried solely by the brakebeam and are readily andconveniently removable therewith.

Changes in the form, proportion, and minor details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention,what

I claim, and desire to secure by Letters Patmy hand in the presence oftwo subscribing 35 witnesses.
